8GB Upgrade |
| Comments: |
Easy installation into 27" i7 iMac (Late 2009). Immediately recognized by OS X. Significant improvement in startup time for both the iMac itself, as well as memory-intensive apps (Photoshop, Logic Studio, VMWare Fusion). |

Payment Trouble |
| Comments: |
The 4GB RAM modules are excellent and no problem at all for my iMac 27-inch 2.8GHz.
As the buyer from Hong Kong, I was in trouble of making payment via PayPal due to unconfirmed address. My delivery address still cannot be confirmed even I had made many times of payment via PayPal for online purchases. Eventually, I still need to disclose all details of my credit card to complete the order. |

iMac Upgrade |
| Comments: |
Maxed out my 2009 Core i7 iMac with 4GB modules, which I was pleasantly surprised to see were the same brand that Apple used for the factory 2GB chips. Perform wonderfully, no problems, love having the extra memory available for Photoshop and VMware Fusion. |

Real world performance has gone up, but geekbench score went down. Even though I went from 4gb to 12gb. I've read that it's something to do with channel speeds (????)
Still screaming though!
Plus Pro Memory was great to work with! |

Cheap, Easy and Fast |
| Comments: |
Best prices i could find, the Apple Store charges $600 +tax for the same amount of ram (a 75% discount) . Easy to install if you can use a screwdriver. Fast Fedex Shipping that was also free. |

I ordered the 8G (2x4G) kit for my 27" iMac i7. The machine already had 4G in it, and this kit brought it up to 12G. The memory has been perfect. The machine works perfectly, is lightning fast, and doesn't even breath hard when I have multiple tasks (including multiple VM instances) running. This memory is highly recommended. |
